The Cremona Auditor can successfully drive a 20' x 20' x 8' room. However, despite their 90db/w/m efficiency rating, they need power to sound unconstricted and assertive. Also, being 4 ohm speakers, Auditors do not put most solid state amps in their best sound zone. McIntosh autoformer amps are particularly synergistic with Cremonas and Cremona Auditors. The MA6900 integrated sounds sensational on Auditors and in this case I make a rare recommendation of this amp over the Cary SLI80. A good preamp with a Mac MC252 or MC402 is even better, but that might exceed your space and funds.
If you choose to later add a subwoofer, be careful. Most subwoofers are too slow to mate well with that fast little cone in the Auditor. The Zu Method is an excellent match.
